The price i got for the blu-ray version was £17.99 because it includes 3 levels and 15 ''zany'' characters to choose from, on PSN i think its around £2.00 or £3.00 because it only comes with one level and one character ?i think? you can buy levels for £1.00 ?i think? and the characters are 80p ?i think?
My favorite level would be the museum for the shear fact its just so so fun to smash or grab stuff while you fly through the air.
I hope i persuaded you to buy it because its amazing.
My view: Buy it.
